"Proficiency Proofreading Practice" is an educational Android application developed by Yosry Sallal. The app aims to help users enhance their proofreading skills and become professionals in the field. It offers 100 practical exercises focused on proofreading. Each exercise presents a piece of text with 5 grammatical, spelling, and punctuation errors, and users are required to identify and click on the errors within the text.

The app challenges users by allowing only one incorrect click per exercise. Making multiple incorrect clicks leads to exiting the exercise, prompting users to start over. Detailed explanations accompany error corrections to ensure users derive maximum learning benefits. Additionally, the app conveniently saves user progress, allowing them to resume from where they left off in their proofreading practice.
